Fun fact is Makintocke makes a few good points about psychology and human behaviour^
Also, it wasn't a "you should kill yourself" insult, neither was it a threat (really guys?). Not to mention that MPRA2 didn't complain personally, so I wouldn't consider this complaint relevant anyway.
Mackintoke is an active member of the community, good teamplayer, pleasant to have on your side. I would trade him for many others in a heartbeat.
I would, for one, like the !mute command to come back. Talking shit should be countered by muting, not kicking-banning.
Imho definitely not a ban case.
